“Bought a 1999 Gmc SIERRA 3500 4door 8ft. Bed with 30000 miles on it in 2001. First brake line rusted out in 2005. Second line from front to back rusted and broke 2008. Fuel line rusted and leaked gas all over my driveway 2010. Today that same truck? Is in a repair shop because the frame by the steeringbox and passenger side front rusted and cracked. Its a shame Gmc used such bad materials for their trucks. My truck now has only 97000 miles on it. If it cant be fixed safely the scrap yard is its next stop and a ford will take its place. To bad Gmc you lost another customer.”
NHTSA complaint #10586534, filed 2014-05, 60,000 miles“My 1999 Gmc SIERRA 3500 crew cab was ordered new. I discovered later that it was fitted with a 1998 cab. The design is different and the front doors are longer and heavier resulting in premature hinge failures. I also discovered that it was not equipped with airbags because the 1998 version didn't require them even though I ordered a 1999 which does. I have a VIN on the dashboard showing it as a 1999 and one on the door showing it as a 1998. I just found out about reporting it here.”
